The simple and understandable statement of SMT processing is: attach electronic components such as capacitors and resistors on electronic products with exclusive machines, and weld them to make them stronger and not easy to fall into the air. For example, the high-tech products that we often use today are computers and mobile phones. The internal motherboards are densely arranged with tiny capacitors and resistors. These capacitors and resistors are pasted using SMT patch processing technology and processed by high-tech patches. The capacitor resistance is much faster than manual patching, and it is not easy to make mistakes. SMT is currently a very popular processing technology in my country's electronics industry. Now that SMT chip processing is a processed high-tech product, then I think it also has high demands on the processing workshop. What kind of workshop is needed in detail, let's find out:

SMT chip processing has certain requirements for environmental requirements, humidity and temperature. In order to ensure the quality of electronic components and enable the processing quantity to be completed early, there are several requirements for the working environment:

The first is the temperature request. The best temperature in the plant is 23±3℃ throughout the year, and the limit temperature cannot exceed 15~35℃.

The second is the humidity request. The humidity in the patch processing workshop has a great influence on the quality of the product. The higher the environmental humidity, the electronic components are susceptible to moisture, which affects the electrical conductivity, the welding is not smooth, and the humidity is too low. The air is easy to be dry, and it is easy to generate static electricity. Therefore, when entering the SMT patch processing workshop, the processing personnel also need to wear anti-static clothing. Under normal conditions, the workshop is requested to insist on using (dehumidifier/humidifier) with a constant humidity of about 45%~70%RH.

The other is the cleanliness request. To ensure that there is no smell or dust in the workshop, the interior is clean and clean, and there is no corrosive materials. They will seriously affect the reliability of the capacitor resistance and increase the defects of the chip processing equipment. The maintenance rate reduces the consumption schedule. The best cleanliness of the SMT patch processing workshop is about 100,000.

The above is the application scope of temperature and humidity in the patch processing workshop and the precautions for purchase introduced by Nesta, so please feel free to contact us for more information about temperature and humidity control in the patch processing workshop.
